@gailcalledThat verb agreement ain’t right. It would have to be elevo and demitto.Quae is a pronoun, not a noun. It can apparently mean “something” after certain conjunctions, but not here, I think. I’d really recommend res. Or some noun, at least.Also, in Latin, subject pronouns are normally dropped. You wouldn’t say “ego” unless you want to stress “I (and not someone else)”.

Combining these ideas, I’d say: “Res elevo et demitto” (I lift up and put down things).
Or maybe “Res elevo et eas demitto” (I lift things up and put them down). The second seems more literal, but again, this is a language where pronouns are usually left out, so I think the first would sound more natural to… um… an actual ancient Roman. Am I taking this too seriously?
